Hi,

Has this user ever been able to recieve external mail? Has anything changed? Do the external senders recieve a non-delivery report error? Can you check the SMTP address for the user under ADU&C > Advanced Features > Properties of the user?

Can the user send to an external account and if the message is recieved can you try to reply to the original message.

We had a user account that had a name change, someone at the Help Desk changed the name and then saw that there were problems. We then deleted the exchange mailbox and then createda new mailbox. After no success, we deleted the AD account and started with a new account, now the account can receive internal email but no external email.

Do the senders recieve an NDR? Does e-mail from the Internet go through any SPAM/mail filtering gateway etc? Do you have message tracking enabled can you perform a message track to see if the email comes into your organisation? Did you check the SMTP address on the users account properties?

No, external senders are not receiving and NDR. I checked our Symantec Mail Security Appliance and there is nothing in the quarantine that was inbound for this user. I am using my own gmail account and my verizon account both to test sending to this user. Message tracking is enabled and I cannot find the email coming inbound. I did check and do see the SMTP address in the exchange email addresses tab in the user account.

Can you see the mail hitting the Symantec Mail Security Appliance at your gateway? If message tracking is not showing the mail hitting your Exchange org then the gateway is the likely cause. The other thing I would be doing it trying to send to this user using telnet from an external network connection.

Yes, I can see the mail hitting and passing through the Symantec Mail Security Appliance.  Nothing in the quarantine. I will check using the Telnet when I get home tonight.

I tried Telnet and used a know good address without any problem. I then tried the address that we are having problems with and got the following:

550 5.7.1 Requested action not taken: message refused

Have you enabled any recipient filtering etc? Does the SMTO address for this user match your recipient policy?

There is no recipient filtering, SMTP address matches recipient policy.
